/* ─────────────────────────────────────────────────────────────────────────
   Vortex — the phone.

   The app is a door you stand at, not a dashboard. When something is waiting
   for you it takes the whole screen; when nothing is, the app is almost
   wordless. That is the difference between this and the desktop console, and
   it is structural rather than cosmetic.

   One rule about colour: it only ever means state. The chrome is monochrome,
   and orange / green / red mean waiting / live / failed. If you see colour,
   something is true.
